@bung You do not have an Issues section on your fork. I wanted to ask you if the dependency on libzip can be made optional? (See [my message above](https://forum.nim-lang.org/t/6386#39399) ). The original `nimhttpd` builds and runs fine on my machine (RHEL 6.8), but trying to run your fork fails as I don't have the needed `libzip`.

Awesome! That is the winner! @Araq It would be now cool to bake that into nim :)
Re: Is there a command line one-line to start an HTTP server using Nim?
OK, it builds find after uninstalling `zip` and doing `nimble install zip@#head`. So the correct fix is: 1. Cut a new release of the `zip` nimble package 2. Cut a new release of your `finder` package with updated zip version in its dependency 3. Finally update your `static_server` package with updated finder version in its dependency

I have seen a similar issue on nim devel too. I am trying to create a reproducible example for that. I also see runnableExamples trying to get executed from sequtils.. My Nim module does import sequtils, but there are no runnableExamples in it.

Re: Checking the gcc/g++ versions used to compile nim program vs the dyn linked .so

Checking the gcc/g++ versions used to compile nim program vs the dyn linked .so
Hello, Today I came across this run time error when running a nim compiled program that dynamically linked with an external c++ library .so (let's call it `external_lib_64.so`) could not load: external_lib_64.so compile with -d:nimDebugDlOpen for more information Run So I compiled and ran the nim program with `-d:nimDebugDlOpen` and still that did not give any useful information. I knew that the `external_lib_64.so` was compiled using g++ 6.3.0. By a stroke of luck, it occurred to me that may be I should check the g++ version in my current environment where I was compiling the nim program .. and indeed it was different; it was g++ 8.4.0. Once I switch to g++ 6.3.0, re-compiled the nim program and ran it, that "could not load: external_lib_64.so" error went away and things once again ran fine as before. **Questions to the community:** * Should we need to match the g++ versions this way all the time? I thought that the compiled external_lib_64.so was "bulletproof" now that it was compiled. But apparently not? * @Araq Is it possible for the Nim compiler to detect this g++ version mismatch and throw a better error? This was using the latest stable nim 1.2.0.

Re: Help with set
> there is not need in auto inferring, since type of x well-known before, and > it can not be changed implicitly by Nim rules. It's the job of the compiler to ensure that the type of the value on right hand side matches with the type on left hand side. I cannot rely on the user always doing the Right Thing. It's quite likely the error we see in your second example is a real error because the user put non-int16 values in the set by mistake :)
Re: Help with set
> why does it work with char?
Re: Help with set
Nim is a compiled language. So at the time of compilation, it checks if the
value assigned to a variable fits the type of the variable in the declaration.
Nim auto-infers the type looking at the **right hand side** of an assignment.
So ..
type
CharSet = set[int16]
Run
Nim: OK, you defined a type CharSet that's expected to be a set of only int16
type elements
var
x: CharSet
Run
Nim: OK, you **declared** an x variable of type CharSet
x = {1..9, 15, 45..78}
Run
Nim: _[sees](https://forum.nim-lang.org/postActivity.xml#sees) {1..9, 15,
45..78}.. hmm the value is a set of ints (because the literal **1** (the first
element) is of type int), but... the left hand side x expects a set of int16!!
Abort .. abort ..
\---
Instead ..
x = {1.int16..9, 15, 45..78}
Run
Nim: _[sees](https://forum.nim-lang.org/postActivity.xml#sees) {1.int16..9, 15,
45..78}.. hmm the value is a set of int16s (because the literal **1.int16**
(the first element) is of type int16), and... the left hand side x also expects
a set of int16! We are good :)

You got the colon and parens in reverse order. But I came to say here this. Once you know the consistent style of proc signatures, it's really easy to search for things.

Re: What text editor are you using for Nim?
> Nah, it's a pretty known fact. This is a case that Spiderman's uncle talked about: "With great power comes great responsibility". With the possibility to tweak Emacs anyhow one likes, that also increases the chances of one badly tweaking Emacs. One should not blindly paste configs from other users; one should know exactly what their config is loading. Most of those search results will talk about using `M-x profiler-start` which allows a user to understand what in their Emacs config is causing it to slow down (this exercise, which many people do not do, and just complain about it being slow). If people find their Emacs slow, they should compare with how fast the `emacs -Q` (stock emacs with zero user config, but still fully functional) sessions are. Emacs allows users to customize every aspect of their editor experience and that can be too easy to shoot in one's foot too.
Re: What text editor are you using for Nim?
> And Emacs itself tends to be somewhat unresponsive, as evidenced by the very > first posts in this thread. That's a grossly incorrect generalization. I agree that Emacs has a weak spot when handling long lines. I have been using Emacs for 14+ years, and I never came across that limitation, may be because I code in 2-window frames and thus limit line lengths to roughly 80 chars.

Re: What text editor are you using for Nim?
You are right; may be nim-mode is exacerbating the slowness issue. I haven't come across this issue as I limit the number of chars per line to around 80. Try using `nimpretty` that ships with Nim. With a `longlines.nim` ( [http://ix.io/1QnF](http://ix.io/1QnF) ), running `nimpretty longlines.nim` modifies the same file to this ( [http://ix.io/1QnG](http://ix.io/1QnG) ).
Re: What text editor are you using for Nim?
> Emacs slows down when you have long lines I agree, but that would be a rare case where you have a single line unprettified JSON or something like that. How long are your lines in Nim? I default to 80 chars per line. For Emacs, "too long" lines would be in the range of upper hundreds of chars per line.
Re: What text editor are you using for Nim?
Emacs here, using mostly the default key bindings. About the slowness, you probably just need to disable the `nimsuggest-mode`. I haven't noticed any slowness when editing Nim code (or anything) in Emacs.

Re: timezone in unit tests
I do this in one of my Emacs lisp projects, I set the `TZ` environment variable to `UTC` in my test config. So when the tests run on Travis, it thinks that it lives in the UTC zone, and all time stamps are created accordingly. That way, you don't need to hardcode the time zone in your Nim code, and all time manipulation code will default to the local time zone (set by TZ).. I believe. I haven't tried this with Nim, so just try it out :)

Re: How to compile/view the docs on localhost?
I see that you intend to contribute to the Nim repo, so you would have already done the cloning step in step 1 in the instructions at [https://github.com/nim-lang/Nim#compiling](https://github.com/nim-lang/Nim#compiling). For unix systems, step 2 is `sh build_all.sh`. And then `koch docs` creates the whole Nim documentation website locally.
Re: Help getting this macro to work in a for loop
Thank you! That was a very good explanation; it now helps me understand why macros cannot work in for loops.
